The grid I needed to build a ventilation for the car. There is always ideal due to the dimensions. At workmanship and quality is nothing to complain. Particularly noteworthy is the already integrated Flyscreens, which is quite closely and thus the intrusion of uninvited guests effectively prevented. The rain protection is through the very narrow lamella very good. That in my view (and for the specific purpose) small drawback is the somewhat too small material thickness, whereby the grid is relatively flexible. But that plays a subordinate role for the well actually intended use.
